Abstract (en)
A solid catalyst component and catalyst system, and method for the homopolymerization of propylene or copolymerization of a major amount of propylene with one or more other 1-olefins are disclosed. The solid catalyst component is used in combination with a complex of an alkyl aluminum cocatalyst compound and an electron donor stereoregulating agent. The solid catalyst component is prepared by reacting a silica-containing support material with a magnesium silylamide compound, an electron donor stereoregulating agent, and a halogenated tetravalent titanium compound.
